B.3.2.3 Installing 'gawk' on VMS
................................
To use 'gawk', all you need is a "foreign" command, which is a 'DCL'
symbol whose value begins with a dollar sign. For example:
$ GAWK :== $disk1:[gnubin]gawk
Substitute the actual location of 'gawk.exe' for '$disk1:[gnubin]'. The
symbol should be placed in the 'login.com' of any user who wants to run
'gawk', so that it is defined every time the user logs on.
Alternatively, the symbol may be placed in the system-wide 'sylogin.com'
procedure, which allows all users to run 'gawk'.
If your 'gawk' was installed by a PCSI kit into the 'GNV$GNU:'
directory tree, the program will be known as 'GNV$GNU:[bin]gnv$gawk.exe'
and the help file will be 'GNV$GNU:[vms_help]gawk.hlp'.
The PCSI kit also installs a 'GNV$GNU:[vms_bin]gawk_verb.cld' file
that can be used to add 'gawk' and 'awk' as DCL commands.
For just the current process you can use:
$ set command gnv$gnu:[vms_bin]gawk_verb.cld
Or the system manager can use 'GNV$GNU:[vms_bin]gawk_verb.cld' to add
the 'gawk' and 'awk' to the system-wide 'DCLTABLES'.
The DCL syntax is documented in the 'gawk.hlp' file.
Optionally, the 'gawk.hlp' entry can be loaded into a VMS help
library:
$ LIBRARY/HELP sys$help:helplib [.vms]gawk.hlp
(You may want to substitute a site-specific help library rather than the
standard VMS library 'HELPLIB'.) After loading the help text, the
command:
$ HELP GAWK
provides information about both the 'gawk' implementation and the 'awk'
programming language.
The logical name 'AWK_LIBRARY' can designate a default location for
'awk' program files. For the '-f' option, if the specified file name
has no device or directory path information in it, 'gawk' looks in the
current directory first, then in the directory specified by the
translation of 'AWK_LIBRARY' if the file is not found. If, after
searching in both directories, the file still is not found, 'gawk'
appends the suffix '.awk' to the file name and retries the file search.
If 'AWK_LIBRARY' has no definition, a default value of 'SYS$LIBRARY:' is
used for it.
